Alarm
If
No Data - Causes an alarm to activate if data is not re-
ceived on the port you defined within ID seconds when Yes is
selected (the default condition). To disable the alarm, select
No with the Change softkey.
Correction Factor - Allows you to make minor adjustments to
observed or measured errors in your speed through water cal-
culation. The input value will be multiplied by this value be-
fore it is used in the receiver. The default value is 1,00.
Digital Pulse Input:
Digital Pulse Input Port No. - Select betweenDigital Input Port 1,
or Digital Input Port 2. A single pulse input which is cali-
brated for log pulse rate and the receiver will automatically
make the necessary calculations.
Digital Input Port 1 is pin 3 (black/white) of Cable B connec-
tor and Pulse Input Port 2 in pin 2 (black) of Cable B. Both
ports share pin 1 (shield-GND or power ground) as a common
ground. These input ports are different from the NMEA-0183
Input Ports 1 and 2.
Pulses Pr. Nm - This is the calibrated pulses per speed unit value
that you must get from the speed log manufacturer.
Alarm
If

ceived on the port you defined when Yes is selected (the de-
fault condition). To disable the alarm, selectNo with the Change
softkey.
Correction Factor - Allows you to make minor adjustments to
observed or measured errors in your speed through water cal-
culation. The input value will be multiplied by this value be-
fore it is used in the receiver. The default value is 1.00.
Both input types have a window in the lower portion of the display
which indicates the input value in real time. If you input a calibrated
pulse rate, you can check for the appropriate speed right here.
You will be able to view the speed log information in the NAV4
screen when it is implemented in future software.
